Abstract
A combined trigger and concealing device for an automatic fire protection sprinkler includes a first plate attached to a second plate by a heat fusible material. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler. The trigger device depends a preselected distance from the bottom of the sprinkler body and includes a cover which has an outer dimension which conceals the internal components of the sprinkler from view. The cover includes openings and is dimensioned and positioned to permit heat energy to be received by the inner and outer surface of the trigger device. Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This construction minimizes response time of the sprinkler while maintaining a highly aesthetic appearance.
